HOSE OR PIPE COUPLING.

Specification of Letters Patent.

Patented March 10, 1908.

Application led January 18, 1906. Serial No. 296,637.

other fiuid, and` relates more especially tol couplings for steam or air conveying hose employed in railway car heating and brake appliances.

The object of the invention is to provide a hose or pipe coupling head or member adapted, by i able coup ing of the improved head ormember with opposing pipe coupling heads or members having fixed coupling lugs or projections which may be variably spaced laterally or which may have varying distance from the transverse plane of the joint face of the op osed head; and to effect such interchangeable coupling of hose or pipes with minimum labor of and danger to the operator, and with assurance of maintaining a fluid-tight joint between the coupled hose or pipes.

The invention in its preferred embodiment consists mainly in an improved coupling head or member having a frame movable both transversely and lengthwise of the coupling and provided at one side with multiple j lugs or shoulders which are non-'alined both vertically and transversely and any one of which is adapted to engage a relatively fixed projection or lug on an opposed coupling ead. At its opposite side t e bodily movable frame has suitable means such as cams acting upon a coupling arm movable laterally by the frame cams and movable lengthwise by and with the frame and adapted to permit coupling of both frame and arm lugs or shoulders with lugs or projections which are variably spaced laterally on narrow or wide opposed coupling heads or members, or with lugs which may have varying distance longitudinally'from the transverse plane of the joint face of opposed coupling heads or members. Means such as cams acting on the frame draw the joint faces of the engaged coupling heads or members together to effect nal Huid-tight joint pf the two couplings.

semieautomatlc movements of simple parts, to uickly and easily effectinterchange- The invention also includes certain details of construction and combinations of parts of the improved coupling; all as hereinafter described and particularly pointed out in the ap ended claims.

eference is made to the accompanying drawings forming part of this specification, and in which Figure 1`is a lan view showing the improved coupling ead engaged with a narrow standard coupling head or member. Fig. 2 is a plan view showing the same improved coupling head engaged with a wider coupling head or member. Fig. 3 is a side elevation of the `improved coupling head showing its bodily movable frame raised in full lines and lowered in dotted lines. Fig. 4 is an outer end view of the improved coupling head with its forwardly projecting arm in vertical section at one of its su porting and guiding pins. Fig. 5 is a vertica transverse section taken on the line 5`5in Fig. 1. Fig. 6 is a crosssection through the body of the cou ling taken on the line 66 in Fig. 1 and with) the joint tightening cam removed.' Fig. 7 is a rear face view of the joint-tightening cam. Fig. 8 is a top perspective view of the bodily movable frame as seen from its cam side; and Fig. 9 is a side elevation of av modification of the invention.

Referring first more particularly to Figs. 1 to S of the drawings, the numeral 1 indicates the fiat-sided or transversely squared front body portion of the improved'coupling head with which connects the preferably upturned neck 2 to which a fluid conveying hose or pipe is to be fastened in any approved manner. At the point of meeting of the body 1 and neck 2, are formed shoulders 3 which resist pressure of final tightening of the joint of the coupled hose or pipes as hereinafter more fully explained. The rounded portion of the neck 2 neXt the shoulder 3, provides a bearing for a collar 4 preferably having a handle 5 by which to turn it and also having oppositely located cams 6, 6, which act upon shoulders 7, 7, formed on lugs 8, 8, fixed to a metal frame 9 movably fitted upon the squared coupling body 1.

The coupling frame 9 which is shown in perspectivein Fig. S of the drawings, has considerable movement transversely and in vertical direction upon the coupling body 1, and may also move longitudinally thereon between the cam collar 4 and the enlarged outer coupling nozzle 10 which carries a joint packing or gasket 11. At one side of its forward part the frame 9 has a series of vertically and transversely non-alined coupling lugs or hooks, two such lugs 12, 13, being shown in the drawings. One of these lugs may be engaged independently of the other with the hooked end lug 14 of a forwardly projecting arm 15 on an opposed standard coupling head or member which has the usual undercut coupling lug or projection 16 at the other side of its body portion 17. This body ortion 17 has a neck 18 to which a section of ose or pipe to be coupled is suitably connected. At its side opposite the coupling lugs 12, 13, the frame 9 loosely receives between its front and rear cam-carrying bars 19 20, the inner rear portion 21 of a coupling arrn 22. This arm normally projects forward beyond the frame and has at its outer end a preferably right-angularly formed undercut lug 23 adapted to engage the lug .16 gf ether a narrow or widerl opposed coupling The arm 22, by reason of the fitting of its part 21 between the bars 19, 20 of the frame 9, will always move longitudinally with said frame, but said arm 22 has practically no vertical movement as it is sustained upon two or more steadying pins 24 fixed to the squared coupling body 1 and preferably arranged out of line vertically. A screw 25 threaded into the end of each pin 24 holds to the end of the pin an outer collar 26 between which collar and an inner shoulder 27 on the arm is placed upon the pin a s ring 28 which by its expansion normally ho ds the arm 22 laterally inward on the pins 24 and with the arm shoulders or faces 29 against the outer faces of the cam bars 19, 20, of the frame 9. The arm 22 is slotted at 30 toreceive each pin '24, its collar 26 and s ring 28, to permit ongitudinal movement, o the arm with the frame. 1

The frame bars 19,20, each have a series of stepped cam faces causing or permitting 'the coupling arm 22 to assume lateral bodily adjustments corresponding in number with the number of coupling lugs or hooks such as 12, 13, there may be at the opposite side of the frame. There being two of such coupling lugs shown in the drawings, it is necessary to provide for but two different bodily lateral semi-automatic adjustments of the `arm 22 by the frame 9. This is done by forming on each frame bar 19, 20, lower and upper cam faces 31, 32, connected by intermediate inclined faces 33, as more clearly shown in Figs. 4, 5 and 8 of the drawings. One or both of the cam bars 19, 20, of the frame 9 may be detachable to permit convenient assembling of the parts, the bar 19 being so shown and fastened by screws 3'4 to 'the top and bottom plates of the frame.

As thus described the operation of the invention is as follows: If the improved coupling head is to be connected to a narrow standard coupling head or member, as shown in Fig. 1 of the drawings, the operator will simply raise the frame 9 by pulling or pushing it upward upon the squared coupling body 1, and the frame will be automatically held up by the pressure of the springs 28 holding the arm 22 to the lower faces 31 of the cam bars 19 20, below their inclined faces 33. The frame 9 with the arm 22 may now be bodily moved forward on the coupling body 1 to cause the lowermost frame lug 12 to engage behind the relatively fixed lug 14 of a narrow opposed coupling head while the arm lug or projection 23 engages with the iiXed lug 16 ofthe opposed head. The frame coupling lug 13, by being entirely above the plane of the opposed coupling arm 15, does not interfere with said engagement of the frame lug 12 with the arm lug or hook 14. The forward packing 11 of the coupling having been presented to the opposed joint face of the standard coupling, the collar 4 will be turned by its handle 5 or otherwise to cause its cams 6, 6, to draw the frame 9 rearward by action upon the opposed shoulders 7, 7, of the frame lugs 8, 8. This will draw the engaged lugs 12-14, and 23-16, and also the packed joint 11 of the two coupling heads securely together, while the thrust is taken at the coupling body shoulders 3 by the forward face of the cani collar 4, and also at the forward shoulder of the inner portion 21 of the coupling arm 22 in contact with the frame bar 19.

It is obvious that the above described connection of two opposed coupling heads will be effected even if the engaging faces or shoulders of the coupling lugs 14, 16, of the different standard coupling heads vary more or less in longitudinal distance from the transverse plane of the joint faces' of the heads, as in this ease the frame 9 will simply slip foiwv'ard or backward upon the coupling body 1 to aecommodate all such longitudinal variations in distance of the lugs 14, 16, relatively to the joint face, while the slots 30 in the arm 22 allow free longitudinal adjustment of said arm with the frame and relatively to the arm clamping springs 28 and their 'fixed supporting pins 24. The cams 6, 6, by acting upon the frame lugs 8, 8, thus will always lock the frame 9 and arm 2O securely when the packed joint at 11, and the lugs 12-14, and Z3-16, are all properly adjusted, and in manner assuring permanently fluid-tight coupling of the hose or pipes connected to the opposed coupling heads or members.

Should it be necessary to connect the improved coupling head to a wider coupling head or member, as shown in Fig. 2 of the drawings, the operator will simply push the raised frame 9 downward. This will cause the inclined cam faces 33 of the frame to force the coupling arm 22 laterally outward and will permit the arm to rest by its shoulders 29 upon the higher cam faces-32 of both frame bars 19, 20, as the sprin s 28 are compressed between the arm shoul ers 27 and the collars 26 on the fiXed arm-steadying pins 24. The lug 12 on the frame 9, now being below the level of the lug 14 of the opposed wider standard coupling head, the frame lug 13 may readily be hooked behind said lug 14 while the arm lug 23 is hooked behind the lug 16 of the opposed head. When the joint faces at 11 of the two coupling members are placed together and the collar 4 is turned to cause its cams 6, 6, to act upon the frame lugs 8, 8, a final-tight coupling of the two hose or pipes is effected notwithstanding the diference in width of the broader standard connected toa narrow or wide standard coupling member, the rearward pull upon the frame lugs 8, 8, by the cams 6, 6, is always about at the level of the longitudinal axes of the engaged outer portions of the opposin couplings, hence this direct final central pu or draft upon the frame 9 by the cams 6 promotes and maintains square or true seating of the entire area of the two meeting joint faces of the coupling heads to positively assure a fluid-ti ht joint between the coupled heads' or memers of the connected hose or pipe sections.

In the modification shown in Fig. 9 of the drawings, a frame 35 having coupling shoulders 36 at the rear edge of its opposite front side bars 37, is adapted to move vertically and longitudinally upon the squared portion 38 of a rounded coupling head 39. This head has iXed pendent lugs 40 supporting the shaft or pivot 41 of a cam 42 adapted to be turned in va vertically ran ing slot 43 of the frame 35 for locking sai frame. This cam preferably has a lever handle 44 for operating it. With this construction, when the joint packing 45 touches lthe joint face of an opposed coupling head, the cam 42 may be turned in the frame slot 43 to draw back the frame and cause its coupling shoulders 36 to movable transversely and longitudinally on the coupling body and carrying means for coupling engagement with an o posed coupling member, and means for olding said rame in adjusted position on the coupling 2y A hose or pipe coupling having a frame movable transversely and longitudinally on the coupling body and carrying means for coupling engagement with an opposed coupling member, and -means for moving said frame on the coupling body and holding it in adjusted position.
